Argentina coach Felipe Contepomi kept faith on Thursday with the same side that narrowly lost to world champions South Africa for the clash this weekend against Australia.
The Pumas went down 17-10 in a tense one-off test in Buenos Aires three weeks ago, and with no injuries, an unchanged starting XV was named for the match on Saturday in Jujuy.
Experienced flanker Pablo Matera again captains the side with regular skipper Julian Montoya unavailable.
Montoya is one of several senior players not considered due to club commitments. That group also includes Mateo Carreras, Santiago Chocobares, and Marcos Kremer.
